The stars have taken part in a series of powerful ads which give a voice to survivors of human trafficking from the organization, Girls Educational and Mentoring Services (GEMS). These spots, airing on mtvU (MTV’s 24-hour college network), hope to bring awareness and spark a student movement to end modern day slavery.

What can we see in the advertisements?

The strikingly sparse ads feature the words to survivor poetry read by the stars as they are shown in black and white writing.

In addition to the ads, the network and LexisNexis announced that four students from James Madison University won the “Against Our Will Challenge” and $10,000 for creating an digital tool to raise awareness of modern-day slavery. Their interactive video project will debut in early 2013.

mtvU will also partner with the Slavery Footprint app for the second annual “Slavery Footprint Campus Challenge.” The top activitsts will be rewarded with a segment on the network. The first campus challenge was part of the 2011 Clinton Global Initiative Annual Meeting.
